9. Deregulation and the Cost of Trucking. Suppose the government initially limits the number of trucking firms that can haul freight. The market for truck freight is initially served by a single firm that produces 5 million ton miles of service per year, where 1 ton mile is the hauling of 1 ton of freight 1 mile. The newly elected governor has proposed that other firms be allowed to enter the market. At a public hearing on the issue of eliminating the entry restrictions, the manager of the existing firm issued a grim warning: "If you allow entry into the market, 4 or 5 firms will enter, and the unit cost of truck freight will at least triple. There are big economies of scale in trucking, so a single large firm is more cost-efficient than several small firms would be." What's your reaction to this statement?
A.Economies of scale are slight. Unit cost will rise, but not by much
B.According to the graph, there are no economies of scale.
C.Although economies of scale are large, unit cost will not rise because of competition.
D.The manager is correct, large economies of scale will triple unit costs.

B.marginal cost curve above the break-even price.
C.average variable cost curve above the shut-down price.
D.marginal cost curve above the shut-down price.
8.The long-run supply curve shows the relationship between _A_ on the horizontal axis and _B_ on the vertical axis .
Aa.quantity supplied b.priceBa.quantity supplied b. price
9. Sugar Import Ban. The sugar industry is another example of an increasing-cost industry. If the price of sugar is only 11 cents per pound, sugar production is profitable in areas with relatively low production costs, including the Caribbean, Latin America, Australia, and South Africa. At a price of 11 cents, the world supply of sugar equals the amount produced in these areas. As the price increases, sugar production becomes profitable in areas where production costs are higher, and as these areas enter the world market, the quantity of sugar supplied increases. For example, at a price of 14 cents per pound, sugar production is profitable in some countries in the European Union too. At a price of 24 cents, production is profitable even in the United States.
a. If the world price is 13 cents per pound, what areas of the world supply sugar to the world market and the United States?
A.The Caribbean, Latin America, Australia, South Africa, and some countries in the EU.
B.The Caribbean, Latin America, Australia, South Africa, and the U.S.
C.The Caribbean, Latin America, Australia, and South Africa.
D.The Caribbean and Latin America.
b. Suppose the United States bans sugar imports. You predict that the new price of sugar in the U.S. will be at least $__. (Enter your response to two decimal places.)
